What is this fish

TANK UPDATE​

Well, I went to the LFS, bought marine sat, and a hidrometer. I checked the hidrometer in the LFS SW tank, and it showed 1.022 (green mark) and in a FW tank and was 1.000, so I considered the device working proprerly.

Well, went home, prepared some high concentrated SW and started pouring it slowly to the tank, until after an hour I reached a SG of 1.002.

After a matter of hours, the puffer that was sick started swimming around, and now he is feeding with the others. I've fed them artemia, and they go nuts about it. Threw a small piece of raw shripm and they were fightinh over it.

Last night, I got a 1"+ snail apple. Cracked his shell a bit and threw it there. Munching galore.

I never thought suck low salinity change would affect their behaviour in a drastical way.

I will wait till saturday water change to raise the salinity a little more, perhaps to 1.004.
 
Silly Question pato...

Did you go back to that LFS and B!TCH-SLAP them for their lack of knowledge???

or perhaps a gentle nudge to educate them better?

I know the employyes may lack knowledge, but the owner doesn't. He just lacks fish selling principles.


"If you buy the fish, it's yours and I don't care what happens to him unless you are one of my marine costumers, which buy everything from me so I need you to be happy. I'll go to your house and clean the tank for you"
(This should be their motto)​

When I was at his store, he accepted those fish need salt in their tank, but only if you want them to be better than in FW. This is like confusing to me.

I must accept some of the fault. I've been asking for "dwarf" puffers for a long time, and when they got these greens an employee (nice girl) called me. I inmediately started setting a 20 gl tank. When it was ready, I went to the store and got them. I knew those were not dwarves, but I got them anyway with a big doubt in my heart. I reserached some more, asked for sdvice in here and decided to keep them.

Also, another employee offered to change the one that seemd sick, but I refussed, knowing not only the fish would die in their FW tanks, but she'd get into trouble for doing so. She is nice, and tries to be as helpful as possible, so I was not capable of turning her down.

Now I will do my best to keep these fish happy. :D
 
A little update:

I've had these puffers fro about 22 days now. Their water is now brackish, specific gravity 1.006. Been raising their salinity by "2 points" every saturday.

They were dark with a yellow spot on the head when I got them, but now their coloration is gettin lighter and are almost entirely yellow/green. Much more active than they were in the fish store. They have huge appetites. Been feeding with brine shrimp every other day until their bellies are about to burst. They get fat!!!!!!

Saturday, I took an earthworm from my "worm farm" and threw him onto the water. It was 5 seconds before one of the fish ate it WHOLE!!! I was shocked. :eek: :eek: I dropped 2 more for each one of the other puffer and they also ate a whole worm each. Their bellies were huge at that time.

I will keep posting this.

Also, how long could they get along (3 puffers) in the 20 gl. tank I currently have for them.

I have read too that they are actually freshwater for a short period of time while very young :P but I doubt they will have problems with a low brack condition. You will eventually want to keep them at 1.015, and the article says to up it .002 a week, but if there as small as they seem, I would slow that down a bit. Now, this is all from my research, however I have no experience with any puffer other than Carinotetraodon
travancoricus (which you should have gotten) so you may confirm that with the more experienced folks ion the brack forum.

Judging by the pic, and that you thought they were dwarves, Id say they are no more than an inch or so? If thats the case, they should be ok together for a little while. You will definatly need to get rid of 2, and will likely need an upgrade for a single happy healthy one.
